My betta are on a live food diet XD. I have to use a spoon because I have a fear of touching anything remotely leach like, that includes blood worm. I generally rinse my hands under water if I have been doing art before anyway as I always get paint on my hands.

The only time i have stuff on my hands is because my nails are painted and i don't think that will kill the fish.

Before feeding I don't. My hands never actually touch the water when I'm feeding them. However, when I rearrange the tank or do water changes I always wash my hands and rinse them very well.
I kinda figured that the residue couldn't hurt them much since my hands will only be in the tank for a few seconds. Plus their are many things my hands could have come in contact with that I am unaware of.

If you rinse in hot water it dries out your hands so I know I at least don't have to worry about any oils on my hands, lol.

Never before, always after. If I stick my arms into my tank(The larger 5 gallon I just had to prune some leaves), I rinsed that arm off with some vinegar and then with water. After I was done, antibacterial soap and water, absolutely. If I'm just feeding, I use my fingertips and don't get dirty. Just wipe them off. The Omega one pellets aren't smelly like the hikari pellets I used to give. If I'm feeding blood worms, I wash.

I use the tiny spoon that comes with bottles of Atison's Pro to feed my betta his staple pellets (which are now NLS Betta Formula), so I don't really think about washing my hands before feeding times. If I'm handling FD bloodworms, which are really difficult to pick up with a spoon, I make sure to wash my hands before and after feeding.

However, if I'm going to be fiddling around with something inside the tank, or if it's water change day, I always wash my hands before and after doing anything. Basically - if I'm planning to touch anything that will come into direct contact with my fish, I wash my hands neurotically, for my fish's sake.

The main reason I wash my hands is due to the natural oils and lotions I use. This helps to keep the surface scum limited-especially since I don't use a lot of filtration on my tanks to help keep it broke up. And when I feed-it always seems like I gotta stick my hands in the tank for one reason or another....lol.....

Do you have a concern about contaminating the food/getting the fish sick from not washing your hands?
